IMPROVEMENT IN GRAIN-DRILL&

TO ALL WH 0M IT MAY OONGERN:

Be it known thatl, JAMES R. FINCII, of Dayton,Qin-the c0mit'y ot Montgomery, and in the State of Ohio, have invented certain new and useful Improvements in Grain-Drills; zv .-ndo hereby decla.re that the following is a. fu1l, dein, anti exact deseription thereof, reference being had to the accompanying drawings und the letters of reference ma.rked the reon.

In the annexed drawings, makipg a part of thi s specification, A represents a rectangular gra.in-box, of any desireddimensions, provided with holes 61 slqts c c through the bottom, und having the metallic plates B B s'diewed thereto, one end of said plates coming neqrly even with the cehtre of the holes'or s1ots c c. O represents a, long metallic mov able p1atia, provided with slots a a, equal in width und somewhat longer than the plal:es B B, and with a. flange,f, which is prbvid6d wil;h afernale screw, in which Werks the-set-screw g. The plate O is adjusted so that the p1ates B B fit int o the slots a a, and is hold in place, close to the boftom of the box A, by means df the slotted plates D, which are p]aced across the plate C, and gcrewed thl'ough risers, ofequal thickfiess withthe said plate C,izo the.bottom 0F the box A. The set-screw g, sustained by the arm K, works the plafe C baokward und for'ward, und sets it so as to give' any reqhired widt,h und size to the opening or slot in the bottom bf the box A, 0r to close'the same entirely. When thel1ole or slot is entirely closed, the upper surfa.ces Qf the plates B und O, being in the same plane, make a pex-feefly level or even surf,ce in the bottom of the box A, under'the zigzag whee1 oi agitatdx H. F represents n movable metallic gzmg 'orshut-ofl', pro wided with suitable slots, which may be used as a. vibrating or asim a.djustable gaugea.nd is held in place by the plates E E, which are pfovided with slotsd d, which correspond wi th slots in the plate D und the hole e in thq bottom of the grain-box A. G represents a shaft, adjusted in tho grain -box A, und. attache'd in a guitable m alimer by'gearng' to the drive-wheel, and having the zigzag wbeels o1 agih:.t.ora H attached thereto directly ove1 the holes e c, to agitate the grain and c1ea-r awa.y any dirt o1 othe1 fqxeign substu.nce ihm; might otherwise collebi: o1 clog'up the assage throughthe hohes q c zmd slots 02 0l. 'lhc wheels 01' agitators H are provide with fizinges 01 paddles e e, for the' purpose of more effectually agitncing the gmin that mny be in the grain-box A. Having thus fully described my imflention, what I cmim as new, amt desire to secure by Ldtters Patent, is-

- 1. The flafiges e e, in combination with the -Zigzag wheel or agitator H, substant'ially as und for thepurpnse specified.

2. The arrngement of the plates B B with the movable plate r shut-ofl C atta-ehed to the bottom of the grain-box A, substantially as and for the purpose Skat forth.

In testimony tha.t I claim ti1e foregoing, I ha.ve hereimto sei; my band, this 7th day of Dec'ember, 1867.
